Best printable layer is probably ritek. However incase of -R that would probably mean the infamous RITEKG05 and you don't want to use G05.
Yeah it prints nice but it has a terrible reputation when it comes to quality.
TY (while it has it's issues) burns nice is more stable as RitekG05 but it's printable layer isn't that good.
Verbatim - Is probably the best of both worlds burns nice in most cases and printable quality is good.
In other words when it comes to allround performance I suggest verbatim.
When you want fancy pictures and don't care about it becomming unreadable I suggest Ritek.
When you want a disc which will probably burn with the lowest error rate (still a low error rate is no guarantee for long life time !) TY is your option.
